My 2005 Toyota Corolla with 1zz engine usually makes this cold start rattling sound that last 1 to 2 seconds. After that, you don't get to hear the sound again until it's cold. It doesn't short oil, the oil light is not on but sometimes the check engine light comes on and goes off. I use recommended oil. Please I need advice on what to do to eliminate this annoying noise at cold start. Thank you.

Check timing, plugs and coil

How do you resolved this
